Be 1t known that we, PETER HirssELiUs and Jol-IN JADERLUND, citizens of the Unitedv A1-,A2", A. to its vshaft in order to transmit rotary motion States, and residents of Chicago, in the 'from said shaft A ,tojthe shaft B in .varying county of Cook and State of illinois, have in- 'ratios of angular velocity:4 Devicsfor this vented certain new and useful Improve- .p ur ose are m' de as follow'-z, '1 ments in Variablepeed Power Transmitti e pinions 1', A2 and Va e rovided on Gears; and we do hereby declare that thefo the innerfaces of the bores'of'theif hubs ra'dial notches@3 `adayited tob'e severally en gaged by a radially arranged key aLV slid'in endwise in alongitudinah shaft. The said notches aqin the Vbores of. the

lengt of the gearsht are closed a fitting in' annular recesses in'the bores o the hubs as best shown` in Fi formed onor carried by longitudinally arranged sliding-bar e1 mount? 'had to the aecomto the letters of refer? which form a part off' thereof, reference bem drawings, and ence marked thereon,

This invention relates to` variable speed power transmitting gears and .refers -more especially to a gear of that class in which any one of a set of gear wheels rotatively mounted one shaft-and meshingwith another set of gearsfiiced to a second shaft can benoned 1n said groove. Said barls pressed 'outrotatively secured to itsrshaft for Vthe purpose wart. by means of. a spi-ing af arrangediin the of transmittingpower bottom .of the 'groveof sal to the other.

Our inventionlnay'be better understoodby'relerence to the accompanying drawings, in w-hich Figure l is a side elevation of the main operative parts of the gear.

As shown in thesaid drawings, A designates a driving shaft; and B a .driven shaft, disposed pcrpendicnlarly lo each other. Said shafts have rotative bearing ina case or Shelli C which incloses the operative parts of said gear.

The shaft l a short intermediate shaft arranged radially said collar (L andv in a across the gearedface of the gear Wheel Din formed ona collar B* fixed l the r[ )hineof and at'l an acute angle to the to a tubular casing surrounding ars do .not eirtend throughout' -the g lever forv shifting the key the bar a? shifts the From the foregoing, vl1t willbe seen thatl key a4 fromone of 'the gearjvheels.A1, A", A3

Means 'are'provid'ekh for reversing thef di- 'rcet1on rif-rotation ofthe driven shaft, oInj A. Said shaft is rotatively Vmounted y mitted to drive the shaft B in a reverse of which it is driven .gears meshing at its outer end in a beari c. in the casi C and at its inner end in ani tegral with the collar B1. Non-rotatively mounted on the outer end of said shaft E are a pair of beveled gear wheels El and E2; The outermost ear Wheel E1 is located radiallg outside of t 1e gear wheel D and meshes Wit a beveled gear Wheel A4 mounted on the shaft A. The innermost gear wheel E2 has constant meshing engagement'with the beveied annular gear Dl of the gear wheel D. The beveled gear wheel A* is made like the gears A1, A2, A3 and is locked to rotate with the shaftA by the key at. Thus it will be seen that when the gear wheel A is locked to the shaft A rotation of said' shaft is transdirection Athe through the gear Wheels A1, A2, A3.

We claim as our invention z- 1.- In'a variable speed power transmitting device, the combination with two rotative shafts arranged at an angle to each other, of a plurality, of annular concentric gears mounted on one shaft, a. plurality of gear Wheels meshing therewith and looselymounted on the other shaft, means for se arately lookin said ear Wheels to their sha-fp mounted thereon, one of said two connected Wheel bearing shaft and' the4 other meshing with fa plurality of annular concentric gears mounted' on one shaft, a plurality of gear wheels meshing therewith and loosely mounted on the other shaft, means forse arately lockin said terme iate s aft arranged radially of said annular gears, `and two connected gears meshing therewith' and vthe gear wheels to diate shaft arranged radially oi ,j shaft.

ear wheels to their sha t, an i'ngears meshing with a gear wheel on said ear Wheel bearing shaft, and the other'mes ing with one of said annular gears for the purpose set forth.

3. In a variable speed power transmitting device, the combination with a driving 'and a driven shaft arranged at an an le to each other, ofl a wheel or disk mounte on one of said shafts and provided on its lateral face with a plurality of annular, concentric beveled gears, a plurality of beveled gear wheels loosely mounted on the othershat,` means for separately locking their shaft an intermesaid annular gears and provided ,with two connected bevey eled gear wheels, one of which meshes with l one of the annular beveled gears of the disk,

and a beveledvgear wheel normally loose on v the shaft carrying the loosely mounted gears and adapted to be locked thereto, and meshingwith the ,other gear of the intermediate ,i 4. In a variable speed power transmittingr device, the. combination with a shaft, of a gear wheel rotativel vmounted, on said shaft and provided in-its here .with a radial notch and with an annular recess,

a ring detachably secured 1n sald recess and- ,ad'aptedi yto close the adjacent end of saidv notch, and means y for non-rotatively securing said gearwheel to its shaft, comprising =a radially and longitudinally movablekey mounted on the shaft and adapted to engage said notch.
